Bug #: 30465 Summary: BridgeCentral: Invalid floating point operation in mozjs.dll (fldcw in JSDOUBLE_IS_INT32) Product: Wine Version: 1.4 Platform: x86 OS/Version: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: mshtml AssignedTo: wine-bugs@winehq.org ReportedBy: u.dickow@gmail.com Classification: Unclassified
When BridgeCentral 2.2.3 is logged in to a club database on the Internet, it will be fatally hit by an "Invalid floating point operation" dialog box after at most (and often exactly) 9 minutes of operation, i.e. 9 minutes after opening of the main window displaying the very simple web page http://bridge.dk/bridgecentral/nyheder/Welcome/Welcome.html . When you press OK to the dialog box, the application is either completely confused and unusable, or it immediately crashes with 2 more dialog boxes about Access violation in mozjs.dll for read of an address, and the general wine "Serious problem" box. The crash happens completely reproducibly if you just let the application wait at the Welcome window after login and don't touch it.
"Unfortunately" (from a debugging point of view) the bug does _not_ appear when BridgeCentral 2.2.3 uses only a local database, without any Firebird TCP connection. So although anyone can download BridgeCentral from http://bridgecentral.dk/ , you cannot easily reproduce the bug without being a privileged member of a Danish DBf bridge club.
